In an interview, Shkreli, the former CEO of Turing Pharmaceuticals, said that his experience with the pharmaceutical industry has led him to believe that the Democrat nominee has been suffering from Parkinson’s Disease.

Citing his “15 year background in drug discovery and pharmaceuticals,” Shkreli said that her problems walking and talking are “pretty unmistakable signs of Parkinson’s disease.”

While many have tried to explain Hillary’s symptoms as the result of a stroke or concussion, Shkreli said that her troubles walking, in particular her “freezing gait,” is a “cardinal symptom of Parkinson’s disease.”

His evidence for this assessment comes from recent odd footage of Clinton’s behavior on camera. Her perplexing facial movements, problems with walking, and talking could be signs she’s using a long-term treatment of Parkinson’s that causes just those kinds of side effects.

“This is a classic symptom … if you showed someone that symptom and said ‘name the disorder’ it’s not a seizure … that is simply involuntary movement, it’s PD-LID, no doubt about it in my mind,” Shkreli said.

LID, or levodopa-induced dyskinesia, is a not uncommon side effect of the long-term treatment of Parkinson’s with dopamine.

Added together with Hillary’s “freezing gait,” a symptom for which Shkreli helped develop a drug, it “explains everything” — Parkinson’s.
